The Alto Professional TS415 is a compact two-way active PA loudspeaker with a 15-inch low-frequency driver and high-frequency compression driver. Its Class-D amplification delivers 2500 watts peak, while the enclosure supports upright use or a floor-wedge monitor position.

Two balanced XLR/quarter-inch combo microphone/line inputs have separate level controls. A dedicated Bluetooth channel allows wireless audio playback from a compatible phone, tablet or computer, and the XLR Mix output connects additional equipment. True Wireless Stereo links two compatible TS4 speakers for stereo Bluetooth playback.

Four Speaker Use modes, selectable Sub Size settings and the Alto app support system adjustment. The app provides remote Bluetooth level control and custom EQ on compatible iOS or Android devices. A USB charging port supplies power to a connected device; it is not a USB audio interface.

This offer is for one Black TS415 loudspeaker, supplied with a power cable, software download card and manufacturer documentation. A second speaker, subwoofer, stands, microphone, phone, signal cables, cover and suspension hardware are not included. Software downloads and app compatibility follow the manufacturer’s current terms.
